FOLDING TABLE
The invention relates to a folding table, in particular for
an aircraft, comprising a supporting device for a tabletop,
comprising a pull-out device for moving the supporting device
for the tabletop from a substantially vertical stowing position
into a substantially horizontal usage position via an in
particular substantially vertical pull-out position, wherein the
pull-out device has a guiding device for guiding the supporting
device between the stowing position and the pull-out position.
Such a folding table is for example known from EP 1 836 927
Al. This table has a lower housing and a tabletop, which can be
moved from a stowing position arranged vertically in the lower
housing, into a usage position, in the case of which the
tabletop is arranged substantially horizontally. The lower
housing has a cover, which is folded out for pulling out the
tabletop. A supporting frame for the tabletop is fastened in an
articulated manner to supporting arms, which can be slid in
lateral guiding rails via sliding frames. The pivot angle of the
supporting frame relative to the supporting arms is limited by
arcuate guides. The supporting frame can thus not be pivoted
downwards past the horizontal usage position. In addition, four
supporting arms are provided, the one ends of which are
pivotably connected to the supporting arms, and the other ends
of which are arranged so as to be capable of being slid in
guides on the supporting frame. The pull-out of the table
construction is supported against the force of gravity by
springs.
In the prior art, the guiding of the tabletop when being
pulled out is thus disadvantageously separated from the fold-
down mechanism into the usage position. Separate motion
sequences are thus provided, which are not very intuitive and
ergonomic. The construction effort is furthermore also increased
by the larger number of joints. Stability losses can further
appear.

Further embodiments of folding tables are described in US
2009/0078169A1, US2003/0188672 Al, US 2,536,366 and FR 2 802 070.
It is the object of the invention to reduce or to eliminate,
respectively, the disadvantages of the prior art. This object is
solved by means of a folding table comprising a tabletop, with a
supporting device for the tabletop, comprising a pull-out device
for moving the supporting device for the tabletop from a
substantially vertical stowing position into a substantially
horizontal usage position via a substantially vertical pull-out
position, wherein the pull-out device has a guiding device for
guiding the supporting device between the stowing position and the
pull-out position, characterized in that the supporting device
comprises a supporting arm each on opposite sides of the tabletop,
wherein the supporting arms are fixed to the bottom side of the
tabletop, wherein the guiding device has a substantially linear
first guide track for a first guide element on the supporting
device and a second guide track for a second guide element on the
supporting device, which second guide track has a linear segment
and an arcuate segment, wherein the supporting device can be slid
along the linear segment of the second guide track of the guiding
device from the stowing position into the pull-out position and
can be pivoted from the pull-out position into the usage position
along the arcuate segment of the second guide track of the guiding
device, wherein the arcuate segment of the second guide track of
the guiding device has a central angle of substantially 90 ,
wherein, in response to sliding the second guide element along the
arcuate segment of the second guide track, the supporting device,
together with the table top fastened thereto, is pivoted about the
same angle of substantially 90 .
According to the invention, the guiding device has a
substantially linear first guide track for a first guide element
on the supporting device and a second guide track for a second
guide element on the supporting device, which second guide track
2
CA 2982613 2019-03-28
has a linear segment and an arcuate segment, wherein the supporting
device can be slid along the linear segment of the second guide
track of the guiding device from the stowing position into the
pull-out position and can be pivoted from the pull-out position
into the usage position along the arcuate segment of the second
guide track of the guiding device.
The guiding device according to the invention thus has a
first guide track, which runs in a straight line or linearly,
respectively, substantially across the entire length thereof,
and, on the other hand, a second guide track, which has a linear
segment and, directly following the latter, an arcuate segment.
In the first guide track, a first guide element is supported,
which is coupled to the supporting device, in particular a
supporting arm of the supporting device, at a first location. In
the second guide track, a second guide element is supported,
which is coupled to the supporting device, in particular the
supporting arm of the supporting device, at a second location.
The distance between the first location and the second location
is preferably substantially constant. In response to the pull-
out process, the first and second guide element wander along the
first or second guide track, respectively. When the second guide
element reaches from the linear segment into the arcuate segment,
the supporting device is pivoted according to the course of the
arcuate segment of the second guide track. The position of the
supporting device is determined for each pivot angle due to the
2a
CA 2982613 2019-03-28
CA 02982613 2017-10-13
simultaneous guiding of the supporting device via the first
guide element at the linear first guide track. Advantageously, a
positive guiding of the supporting device for the tabletop from
the stowing position via the pull-out position into the usage
position (and vice versa) is thus attained. The embodiment
according to the invention is characterized by a parts-saving
and thus cost-efficient design. The pull-out or folding up
process, respectively, can furthermore be designed in a
particularly intuitive and ergonomic manner. A particularly
stable embodiment can further be attained. The embodiment
according to the invention is furthermore in particular suitable
to accomplish the fold-out of the tabletop by means of a single
drive unit for the pull-out and pivoting process.
To effect a positive guiding of the supporting device
between the substantially vertical pull-out position and the
substantially horizontal usage position of the tabletop, it is
favorable, when the arcuate segment of the second guide track of
the guiding device has a central angle of substantially 90 . The
arcuate segment of the second guide track thus describes an
angle of substantially 90 , while the corresponding segment of
the first guide track runs substantially linearly. In response
to sliding the second guide element along the arcuate segment of
the second guide track, the supporting device, together with the
table leaf fastened thereto, is pivoted about the same angle of
substantially 90'.
To support the tabletop on opposite sides, it is
advantageous, when the pull-out device has two guiding devices
for guiding one supporting arm each of the supporting device.
Both guiding devices are preferably embodied substantially
identically. On the one hand, each guiding device thus has a
first guide track comprising a linear course, in which a first
guide element, which is connected to the supporting device, can
be slid. Each guiding device furthermore has a second guide
track, in which a second guide element, which is connected to
the supporting device, can be slid. The second guide track in
3
CA 02982613 2017-10-13
each case has an arcuate or curved second segment, respectively,
by means of which the pivoting of the supporting device between
the pull-out position and the usage position is accomplished.
The first and second guide element are connected to the
supporting arm of the supporting device at different
longitudinal positions. The positive guiding of the supporting
device or of the tabletop fastened thereto, respectively, can
thus be attained.
With regard to a structurally simple embodiment, which can
be produced in a cost-efficient manner, it is advantageous, when
a plate element, on which the first and the second guide track
are embodied, is provided as guiding device. The first and the
second guide track are preferably provided adjacently on the
plate element. The first guide track is preferably formed by an
elongated passage opening of the plate element comprising a
substantially constant width, so that the first guide element
protrudes from the side of the supporting device through the
passage opening onto the side of the plate element, which faces
away from the supporting device. In contrast, the second guide
track can be formed by a depression of the plate element, in
which depression the second guide element, in particular a guide
pin, which is rigidly connected to the supporting device, is
guided.
For automatically pulling out and pivoting the tabletop from
the stowing position, it is favorable, when the guiding device
is connected to a drive unit, preferably an electric motor, by
means of which the supporting device can be moved from the
stowing position to the usage position via the pull-out position.
It is particularly preferred, when a single drive unit is
provided in order to initially slide the supporting device from
the stowing position into the pull-out position and then to
pivot the supporting device from the pull-out position into the
usage position. This embodiment is made possible in that the
guiding device initially effects a positive guiding of the
supporting device along the linear segments of the first and
4
CA 02982613 2017-10-13
second guide track and then along the arcuate segment of the
second guide track, while the first guide track continuous its
linear course.
According to a preferred embodiment, the drive unit is
equipped to move the first guide element along the first guide
track of the guiding device, wherein the second guide element is
preferably guided passively along the second guide track of the
guiding device. In the case of this embodiment, the first guide
element is driven, whereas the second guide element is guided
passively, i.e. without its own drive, along the second guide
track.
To provide for the pull-out and pivoting of the tabletop by
means of a particularly simple, reliable drive unit, it is
favorable, when the drive unit is equipped to set the first
guide element into rotation, wherein, on the supporting device,
the first guide element is connected to a power transmission
element, by means of which the rotation of the first guide
element can be converted into a linear movement of the first
guide element along the first guide track. The drive unit is
thus connected to the first guide element, which, in the driven
state, performs a rotation. The drive unit is preferably located
directly on the first guide element, which is embodied as drive
shaft in this embodiment. According to a preferred embodiment,
two guiding devices are provided on opposite sides of the
folding table, wherein the first guide element, which is
embodied as drive shaft, is used for both guiding devices. In
the case of this embodiment, it is furthermore favorable, when
the supporting device, in particular a supporting arm of the
supporting device, is rotatably connected to the first guide
element. In the case of this embodiment, a power transmission
element is further provided, which absorbs the rotation of the
first guide element and transforms it into a sliding of the
first guide element along the first guide track.
The sliding of the first guide element can be accomplished
in a particularly safe and reliable manner, when a gearwheel is
5
CA 02982613 2017-10-13
provided as power transmission element, which gearwheel meshes
with a toothed rack in response to the movement of the first
guide element along the first guide track, wherein the toothed
rack preferably has substantially the same length as the first
guide track of the guiding device. In the case of this
embodiment, the gearwheel is preferably connected to an end of
the first guide element in a rotatably fixed manner. It is
particularly preferred, when the first guide element is used for
two guiding devices on opposite sides, wherein each end of the
first guide element is connected to a gearwheel, which runs on a
corresponding toothed rack. The first guide element preferably
passes through a passage opening of the guiding device, which
passage opening forms the first guide track, to the side of the
guiding device, which faces away from the supporting device. In
the case of this embodiment, the end of the first guide element,
which passes through, is connected in a rotatably fixed manner
to the gearwheel, which engages with the correspondingly formed
toothed rack. In the driven state of the first guide element,
the gearwheel thus wanders upwards or downwards, respectively,
along the toothed rack, depending on the drive direction.
To be able to accomplish the move between the stowing
position and the usage position of the tabletop with the
smallest possible power drain of the drive unit, a spring
element, which counteracts the pivoting of the supporting device
in the direction of the usage position and/or which supports the
pivoting of the supporting device from the usage position in the
direction of the pull-out position, is provided according to a
particularly preferred embodiment. In response to the pivoting
of the supporting device from the pull-out position into the
usage position, the spring element is tensioned under the
influence of the dead weight of the supporting device or of the
tabletop, respectively. In the usage position, the spring
element is thus present in the tensioned state. In response to
the pivoting of the tabletop from the usage position into the
pull-out position, the stored tensioning energy of the spring
6
CA 02982613 2017-10-13
element is released, in order to support the lifting of the
supporting device along with the tabletop. In the pull-out
position, the spring element is preferably present in the
relaxed state.
A further spring can furthermore be provided, by means of
which the sliding of the supporting device from the stowing
position into the pull-out position is supported. In response to
the sliding of the supporting device from the pull-out position
into the stowing position, the further spring is tensioned. A
helical spring is preferably provided as further spring, which
is tensioned or relaxed, respectively, by means of a rotation of
the first guide element.
In order to provide the spring force in response to folding
out or folding in the tabletop, respectively, in sections, it is
favorable, when the spring element is connected to a pivot lever,
which can be pivoted against the force of the spring element by
means of the first or the second guide element on the supporting
device. On one end, the pivot lever is supported about a
stationary pivot axis, which preferably extends substantially in
the horizontal direction. The one end of the spring element, the
other end of which is supported in a stationary manner, engages
on the other end of the pivot lever. During its guided movement,
the first or the second guide element thus strikes against the
pivot lever in the direction of the usage position. In the
struck state, the pivot lever is pushed upwards by means of the
first or second guide element, respectively, wherein the spring
element is tensioned with the support of the weight of the
supporting device along with the tabletop. In response to the
pivoting of the supporting device together with the tabletop
from the usage position into the pull-out position, the
tensioning energy of the spring element is transmitted via the
pivot lever to the first or second guide element, respectively,
so that the lifting of the supporting device together with the
tabletop is supported. In the phase of highest load, the drive
unit can thus be supported with the pretensioned pivot lever as
7
CA 02982613 2017-10-13
a result of the dead weight of the supporting device or of the
tabletop, respectively. This embodiment has the advantage that
the maximum drive force, which is to be provided by the drive
unit, can be reduced. A comparatively weak drive unit can thus
be used in order to pivot the supporting device together with
the tabletop upwards from the usage position into the pull-out
position. During the sliding of the supporting device between
the storage position and the pull-out position, the spring
element is preferably present in the relaxed state.
According to a particularly preferred embodiment, the
distance between the point of application of the first or second
guide element, respectively, on the pivot lever and the pivot
axis of the pivot lever is larger in the case of a first pivot
angle of the supporting device in response to pivoting from the
substantially vertical pull-out position in the direction of the
substantially horizontal usage position, than in the case of a
second pivot angle of the supporting device. In the case of this
embodiment, the force transmission from the pivot lever to the
first or second guide element, respectively, which struck said
pivot lever, is thus a function of the pivot angle of the
supporting device. The variable force transmission results from
the lever relationships between the pivot leer and the first or
second guide element, respectively, which engage therewith. The
larger the distance between the point of application of the
first or second guide element, respectively, on the pivot lever
and the pivot axis thereof, the smaller the torque, which the
pivot lever transmits to the first or second guide element,
respectively. In response to pivoting the supporting device
upwards from the usage position, the drive unit can thus be
maximally supported specifically in the phase of highest load
effect.
For this purpose, it is furthermore favorable, when the
distance between the point of application of the first or second
guide element, respectively, on the pivot lever and the pivot
axis of the pivot lever is larger in the case of a third pivot
8
CA 02982613 2017-10-13
angle of the supporting device in response to pivoting from the
substantially vertical pull-out position in the direction of the
substantially horizontal usage position, than in the case of the
second pivot angle of the supporting device. In response to
pivoting the supporting device from the pull-out position into
the usage position, the pivot lever in the struck state of the
first or second guide element, respectively, is pivoted against
the force of the spring element, wherein the arm of the force,
which is formed between the first or second guide element,
respectively, and the pivot axis of the pivot lever, varies,
depending on the pivot angle of the supporting device.
In the case of this embodiment, it is further preferably
provided for the first pivot angle of the supporting device to
be smaller than the second pivot angle of the supporting device,
which is smaller than the third pivot angle of the supporting
device. In response to pivoting the supporting device from the
pull-out position into the usage position, the supporting device
consecutively runs through the first pivot angle, the second
pivot angle, and the third pivot angle, wherein the force
transmission from the spring-loaded pivot lever to the first or
second guide element, respectively, reaches a maximum with the
second pivot angle.
To return the pivot lever into the first angularity in
response to folding up (folding in) the supporting device, it is
favorable, when the pivot lever is pretensioned in the direction
of a first angularity, which corresponds to the first pivot
angle of the supporting device, by means of the spring element,
wherein a stop element for limiting the pivoting of the pivot
lever to the first angularity is provided.
So as to be able to adjust the spring characteristic in
response to the pull-out or pivoting process, respectively, it
is favorable, when the stop element is connected to a control
element, in particular an adjusting screw, by means of which the
first angularity of the pivot lever can be adjusted.
9
CA 02982613 2017-10-13
If at least two fastening locations, which are spaced apart
from one another in the longitudinal direction of the first
guide track, are provided for the selective arrangement of the
pivot axis of the pivot lever, the point in time, at which the
force transmission from the pivot lever to the first or second
guide element, respectively, starts, can be changed.
According to a first preferred embodiment, the substantially
linear first guide track of the guiding device and the linear
segment of the second guide track of the guiding device extend
substantially in the vertical direction.
For the purpose of this disclosure, the information about
location and direction, such as "horizontal", "vertical",
"upper", "lower", etc., refers to the assembled usage state of
the folding table, when being used in an aircraft, it refers to
the horizontal bottom surface of the aircraft.
In the case of this embodiment, it is favorable, when a
cladding element is provided, which can be pivoted between a
position, which closes a pull-out opening for the supporting
device, and a position, which releases the pull-out opening for
the supporting device. The cladding element can preferably be
pivoted about a substantially horizontal pivot axis. The
cladding element can form the upper side of a housing, by means
of which the folding table is installed in particular into an
armrest or a side cladding of an aircraft.
To design the operation to be particularly simple, a switch
for activating the drive unit is preferably provided, which
switch can be operated by pivoting the cladding element. In the
case of this embodiment, the cladding element can strike against
the switch or can be lifted off it, respectively, in order to
initiate the pull-out process, starting in the stowing position.
Vice versa, the switch can be operated via the cladding element,
in order to initiate the fold-in process, starting in the usage
position. The switch can be connected to the drive unit via a
control unit for this purpose.
CA 02982613 2017-10-13
According to an alternative preferred embodiment, the pull-
out device has a tilt mechanism for tilting the guiding device
for the supporting device from the substantially vertical
stowing position into an initial position, which is inclined
relative thereto. In the case of this embodiment, a fixed or
non-pivotable cladding element, respectively, can be provided on
the upper side of the folding table, which cladding element, in
the assembled operating state, is preferably arranged
substantially horizontally. In order to bring the folding table
from the stowing position into the usage position, the tilt
mechanism, by means of which the at least one guiding device is
tilted about a preferably substantially horizontal pivot axis,
is initially activated. The supporting device can then be moved
from the stowing position into the usage position via the pull-
out position by means of the drive unit, wherein, in the tilted
state, the supporting device together with the tabletop can be
guided past the immovable cladding element. In the case of this
embodiment, a switch can also be provided, which is connected to
the drive unit via a control unit. For example, a push switch
can be provided on the fixed cladding element.
The invention will be discussed in more detail below by
means of preferred exemplary embodiments, to which it is not to
be limited, however. In the drawing:

Figs. 14 to 19 show a view of a further embodiment of the
folding table according to the invention, which folding table is
initially brought from the stowing position (Fig. 14) into a
tilted initial position (Fig. 15) in response to the fold-out
process, is then slid upwards into a pull-out position (Fig. 16),
is folded into an intermediate position (Fig. 17), is then
tilted into the usage position (Fig. 18), wherein the tabletop
is finally folded out (Fig. 19).
Fig. 1 shows a folding table 1, which is installed into a
side cladding 2 of an aircraft 3. In the shown stowing position,
the folding table 1 is completely hidden in the side cladding 2.
The side cladding 2 has various cladding elements, wherein a
cladding element 4 on the upper side can be pivoted about a
horizontal pivot axis, in order to release or to close,
respectively, a pull-out opening 5 for pulling out the folding
table 1. The folding table 1 has a tabletop 6, which, in the
shown embodiment, has a front part 7 and a rear part 8. The
front part 7 and the rear part 8 of the tabletop 6 are connected
12
CA 02982613 2017-10-13
to one another via hinges, wherein the front part 7 can be
folded by 1800 to the rear part 8.
As can be seen from Figs. 2 to 10, the tabletop 6 is
attached to a supporting device 9, which has a supporting arm 10
each on opposite sides of the tabletop 6. The supporting arms 10
are fixed to the bottom side of the tabletop 6 (i.e. located
opposite the usage surface of the tabletop 6). To move the
supporting device 9 for the tabletop 6 from the stowing position,
in which the tabletop 6 is arranged substantially vertically,
into a usage position, in which the tabletop 6 is arranged
substantially horizontally, a pull-out device 11, which will be
discussed in more detail below, is provided. The pull-out device
11 has a guiding device 12, by means of which the supporting
device 9 is guided during the entire fold-out process, i.e. from
the stowing position into the usage position via the pull-out
position. In order to evenly lift the folding table 1 on both
sides, the pull-out device 11 has two guiding devices 12 for
guiding one supporting arm 10 each of the supporting device 9.
As can in particular be seen from Figs. 8 to 10, the guiding
device 12 has a straight-lined or linear first guide track 13,
respectively, in which a first guide element 14 is guided on the
supporting device 9. Adjacent to the first guide track 13, the
guiding device 12 furthermore has a second guide track 15, which
consists of a linear segment 16 and of a directly following
arcuate segment 17. The supporting device 9 is connected to a
second guide element 18, which is guided along the second guide
track 15. When in use, the supporting device 9 is initially slid
upwards into the pull-out position, starting in the stowing
position, along the linear segment 16 of the second guide track
15 of the guiding device 12, and is then pivoted from the pull-
out position into the usage position along the arcuate segment
17 of the second guide track 15 of the guiding device 12.
As can further be seen from Figs. 8 to 10, the arcuate
segment 17 of the second guide track 15 of each guiding device
12 has a central angle of substantially 90 , which corresponds
13
CA 02982613 2017-10-13
to the pivot angle of the supporting device 9 from the pull-out
position into the usage position. In the shown embodiment, each
guiding device 12 is formed by a plate element 19, on which the
first 13 and the second guide track 15 are embodied in one piece.
As can be seen from Fig. 2 (schematically), the guiding
device 12 is connected to a drive unit 20 (not marked in Figs. 3
et seqq.), by means of which the supporting device 9 can be
moved from the stowing position into the usage position via the
pull-out position. In the shown embodiment, the drive unit 20 is
formed= by means of an individual electric motor, which is
equipped to move the first guide element 14 along the first
guide track 13 of the guiding device 12. The second guide
element 18 is meanwhile passively guided along the second guide
track 15 of the guiding device 12. The drive unit 20 is coupled
to the first guide element 14 in such a way that the first guide
element 14 is set into rotation. The first guide element 14 is
connected to a force (power) transmission element 21, by means
of which the rotation of the first guide element 14 is converted
into a linear movement of the first guide element 14 along the
first guide track 13. In the shown embodiment, a gearwheel 22,
which is connected to the free end of the first guide element 14
in a rotatably fixed manner, is provided as force transmission
element 21, which is guided through the first guide track 13 to
the side of the guiding device 12 which faces away from the
drive unit 20. The gearwheel 22 runs on a stationary toothed
rack 23, which substantially has the same length as the first
guide track 13 of the guiding device 12.
As can further be seen from Fig. 11 to 13, the folding table
1 also has a spring element 24, which, in response to being
folded out, counteracts the pivoting of the supporting device 9
in the direction of the usage position, and which, in response
to being folded in, supports the pivoting of the supporting
device 9 from the usage position in the direction of the pull-
out position. In the shown embodiment, a helical spring is
provided as spring element 24. The one end of the spring element
14
CA 02982613 2017-10-13
24 is supported in a stationary manner. The other end of the
spring element 24 is connected to a pivot lever 25, which can be
pivoted against the force of the spring element 24 by means of
the first guide element 14 on the supporting device 9.
As can further be seen from Figs. 11 to 13, the distance
between the point of application of the first guide element 14
on the pivot lever 25 and the pivot axis 26 of the pivot lever
25 is larger in the case of a first pivot angle of the
supporting device 9 while pivoting from the vertical pull-out
position in the direction of the horizontal usage position, than
in the case of a second pivot angle of the supporting device 9.
The distance between the point of application of the first guide
element 14 on the pivot lever 25 and the pivot axis 26 of the
guide lever 25 in the case of a third pivot angle of the
supporting device 9 while pivoting from the vertical pull-out
position in the direction of the horizontal usage position is
furthermore larger than in the case of the second pivot angle of
the supporting device 9. When the folding table 1 is folded out,
the supporting device 9 consecutively passes through the first
pivot angle, second pivot angle and third pivot angle. In the
position according to Fig. 5, the distance between the axis of
rotation of the first guide element 14 and the pivot axis 26 of
the pivot lever 25 is minimal, whereas the distance between the
axis of rotation of the first guide element 24 and the free end
of the pivot lever 25, with which the spring element 24 engages,
is maximal. Due to this lever ratio, the force transmission from
the pivot lever 25 to the first guide element 14 is maximal in
this position.
As can further be seen from Figs. 11 to 13, the pivot lever
25 is pretensioned in the direction of a first angularity, which
corresponds to the first pivot angle of the supporting device,
by means of the spring element 24. To limit the pivoting of the
pivot lever 25 to the first angularity, a stop element 27 is
provided. The stop element 27 is connected to a control element
28 in the form of an adjusting screw, by means of which the
first angularity of the pivot lever 25 can be adjusted, depending
on the application. A plurality of, in the shown embodiment three,
fastening locations 29, which are spaced apart from one another in
the longitudinal direction of the first guide track 13, for
selectively arranging the pivot axis 26 of the pivot leer 25, are
furthermore provided.
In the embodiment of Figs. 1 to 10, the linear first guide
track 13 of the guiding device 12 and the linear segment 16 of the
second guide track 15 of the guiding device 12 extends
substantially in the vertical direction, wherein the guiding
device 12 is arranged in a stationary manner. In the case of this
embodiment, the cladding element 4 can be pivoted between a
position, which closes a pull-out opening 5 for the supporting
device 9, and a position, which releases the pull-out opening 5
for the transporting device 9. To activate the drive unit 20, a
switch is provided, which can be operated by pivoting the cladding
element 4.
In the embodiment of Figs. 14 to 19, the pull-out device 11,
in contrast, has a tilt mechanism 32 (which is only marked
schematically), for tilting the guiding device 12 for the
supporting device 9 from the substantially vertical stowing
position (see Figs. 14) into an initial position, which is inclined
thereto (see Fig. 15). In the case of this embodiment, the cladding
element 4 is arranged so as to be immovable or stationary,
respectively. In the tilted position, the folding table 1 is guided
past the cladding element 4 into the pull-out position (see Fig.
16), in which the supporting device or the tabletop, respectively,
is arranged substantially vertically, i.e. inclined only about the
tilt angle of the tilt mechanism 32. The tabletop 6 is then
initially tilted into an intermediate position (see Fig. 17),
before the guiding device 12 is tilted back into the vertical usage
position (see Fig. 18). The two-part tabletop 6 is finally folded
apart.
